Which of the following is NOT a pre-analytic variable?
What would be primarily affected when a sample is analyzed by diffent people?
When the sum of all values is taken and it is divided to the number of samples tested, what is being calculated?
In the Clinical laboratory, to calculate for the standard deviation, a lab must establish how control runs?(minimum)
The following Values are taken from a control run for a new glucose analyzer, assuming that the confidence limit for the control is +/-5mg/dl from the mean of 90mg/dl, what conclusion would be made from the analyses done?
If a standard analytical method is to be replaced by a more SENSITIVE method it should be able to?
a)Detect the analyte in a smaller quantity than that of the standard
b)Detect the analyte in a different samples
c)Test positive if the analyte is present in other samples than the sample normally used in the standard method
d)Test negative if the analyte is not present in sample
This is the ability of an analytical method measure only the analyte of interest even in the presence of interfering substances
Which is NOT a property of a standard?
